Considering this is a remake of a mobile game with micro transactions from 4 years ago (which have been removed in this version), it's actually really good fun. It's a great bullet hell game, very pretty models and environments, tight controls and a decent challenge. It's also really easy to see where you are and why you died which is often a difficult thing to get right in this genre. Only two drawbacks: 1, You can tell it used to have micro-transactions. There's a ton of grinding the same stages over and over to get enough stars for upgrades which is repetitive. 2, loading times. Runs can be over fairly quickly, and 20 second load times every time you restart gets old fast.
